William Lee Beach Jr., 65, who was part owner of a Rockville electrical contracting firm, died Aug. 24 at Washington Hospital Center from complications of heart surgery. He lived in Gaithersburg.

Mr. Beach lived in the Washington area his entire life. He was born in the District and graduated from Archbishop Carroll High School. He served in the Coast Guard Reserve and attended the University of Maryland before embarking on a career as an electrician.

After a four-year apprenticeship, during which he became a licensed electrician, Mr. Beach was a foreman for the Walter Truland Corp. and for HMS Co., two electrical companies later absorbed by other firms. In 1978, he joined T.A. Beach Corp., an electrical contracting company in Rockville founded by his cousin, Thomas A. Beach, specializing in large-scale commercial projects.

Mr. Beach, who had a share of the company's ownership, was labor manager for 10 years and later was a company administrator. He was involved in the company's overseas operations, in which electrical work was installed in U.S. embassies.

He was vice president when the company was sold in 1998 to American Residential Services, which was later purchased by ServiceMaster. Mr. Beach continued to work for the merged company, managing internal safety programs, until he retired in 2003.

For 15 years, he was a youth soccer and basketball coach with the Montgomery County Department of Recreation, Montgomery Soccer Inc. and the National Capital Soccer League. He was also an official with the Seneca Soccer Association.

Survivors include his wife of 38 years, Mary Walter Beach of Gaithersburg; two sons, William L. Beach of Raleigh, N.C., and Bradley J. Beach of Owings Mills, Md.; his mother, Eileen D. Beach of Rockville; and a brother, Gerald T. Beach of Rockville.
